“His feet hit the mat, and almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child.” That is Kaitlin Hill, a mother who watched a trampoline park break her three-year-old son’s femur. Her warning post was shared 240,000 times. We read it at our firm. So did every parent of an injured child in the City of Hideaway who has since stood at a hospital bedside, listening to a surgeon explain what happens when a growth plate is destroyed.
One bounce. One bad landing. One broken neck. That is all it takes at a commercial trampoline park or on a poorly maintained backyard mat in the City of Hideaway. If your child was hurt in the City of Hideaway, the first thing we will tell you is this: what happened was not an accident—it was the predictable output of a business decision.
In Harris County, a jury awarded $11.485 million—including $6 million in punitive damages—against the operator of Cosmic Jump after a 16-year-old fell through a torn trampoline slide onto concrete and suffered a traumatic brain injury. The waiver was signed. The jury found gross negligence anyway. That remains the largest reported jury verdict against a U. S. commercial trampoline park, and it happened right here in Texas. At Attorney911, led by Ralph Manginello with over 25 years of experience, we specialize in making corporate defendants accountable for exactly these kinds of choices.
For two decades, Ralph Manginello has been fighting for injury victims in the City of Hideaway and throughout Texas. Our managing partner, admitted to the Southern District of Texas, brings a level of federal litigation experience that most personal injury firms cannot match. We have gone head-to-head with multi-billion-dollar entities like BP, Walmart, and Amazon. The parent conglomerates behind national trampoline park chains—Sky Zone, Inc. (backed by Palladium Equity Partners) and Unleashed Brands (the Seidler-owned parent of Urban Air)—hire the same caliber of corporate-defense firms we have already beaten.
The Standard of Care: Why Your Injury Was Preventable
A trampoline injury in the City of Hideaway happens because a safety floor was ignored. The American Academy of Pediatrics (AAP) has formally advised against recreational trampoline use since 1999, reaffirming this position in 2012 and 2019. Despite 25 years of medical consensus, manufacturers like Jumpking and Skywalker continue to sell a product they know send 300,000 people to the ER every year.
Commercial parks in and around the City of Hideaway, like Urban Air or iJump in nearby Tyler, claim to meet “industry standards.” We know those standards better than they do. ASTM F2970 is the safety specification the trampoline park industry actually wrote about itself. When a park violates its own self-authored rules—on attendant-to-jumper ratios, foam pit depth, or age-separated jumping zones—it is not just negligent; it is acting with conscious indifference.
While ASTM F2970-22 is a voluntary standard in 39 states, the international community has moved toward mandatory protection. EN ISO 23659:2022 is the mandatory European standard for trampoline parks. Australia mandates AS 4989:2015. The United States remains an outlier, leaving Texas families to rely on the firm they hire to enforce a duty of care that the state legislature has yet to mandate.
We don’t just “handle” personal injury cases. We have built our practice around the medicine and the physics of catastrophic injury. We currently litigate a $10 million lawsuit against a major university involving rhabdomyolysis and acute kidney failure—the exact same muscle and organ breakdown we see in crushed-limb and extended-exertion trampoline injuries. We know the creatine kinase trajectories, the renal tubular pathology, and the institutional-defendant patterns that win these cases.
Call 1-888-ATTY-911 today. We work on a contingency fee basis, meaning there is no fee unless we win. We advance every investigation cost—including the biomechanical engineers, pediatric specialists, and ASTM compliance experts your case requires.
The Mechanisms of Injury: The Physics of the City of Hideaway Trampoline Parks
The “freak accident” defense is a myth. Every injury at a park serving City of Hideaway families has a named mechanism, a known frequency, and a specific ASTM violation attached to it.
The Double-Bounce Catapult (Through-Line #9)
This is the signature injury of the commercial court. When a 200-pound adult lands on a bed at the same instant an 80-pound City of Hideaway child pushes off, energy transfer multiplies the child’s launch force by up to 4x. The child isn’t jumping anymore; they are a projectile. ASTM F2970 requires age and weight separation specifically to prevent the femur and tibia fractures that follow.
The Foam Pit Failure
Foam pits in older City of Hideaway-area facilities often look soft but hide a hard subfloor. A jumper who lands head-first in a pit compacted below the 8-inch ASTM specification faces axial loading on the cervical spine. This is the mechanism that paralyzed Damion Collins in a Kansas Urban Air, resulting in a $15.6 million award despite a signed waiver. The arbitrator in that case found a “systemic failure” to implement safety changes.
The Adjacent Attraction Trap
Modern parks are no longer just trampolines. They are family entertainment centers bolting on dangerous attractions like the Sky Rider zipline-coaster or indoor climbing walls.
- Sky Rider Strangulation: Documented patterns across Urban Air locations (Newnan, GA; Bloomingdale, IL) involve harness cords tangling around children’s necks.
- Climbing Wall Falls: In 2019, 12-year-old Matthew Lu died at an Altitude park after employees failed to secure his harness, and he fell 20 feet onto concrete. The park publicly admitted to “human error” and removed the wall—evidence of feasibility and control we use to establish liability.
Extended-Jumping Rhabdomyolysis
Imagine a hot Saturday in East Texas. Your child jumps for 90 minutes straight in a facility running near 85°F, drinking only soda. They arrive at an ER two days later with “cola-colored” urine and acute kidney failure. This is exertional rhabdomyolysis. Because of our active $10 million UH rhabdo case, we have the medical expert network ready to link your child’s kidney damage to the park’s failure to provide hydration protocols and rest breaks.
Liable Parties: Piercing the 5-Layer Stack in the City of Hideaway
When we sue for a City of Hideaway trampoline injury, we don’t just sue the building. We pierce the corporate architecture designed to hide the money.
| Layer | Entity Type | Why We Name Them |
|---|---|---|
| 1. Operator LLC | The Local Park | Direct liability for the teenagers on the court who weren’t watching. |
| 2. Franchisee | Multi-Unit Owner | Responsible for regional training and hiring failures. |
| 3. Franchisor | Sky Zone/Urban Air/Altitude | They write the safety manual. When they fail to audit compliance, they are liable. |
| 4. Parent Company | Sky Zone, Inc. / Unleashed Brands | The deep money. They set the margin targets that force staffing cuts. |
| 5. Private Equity | Palladium / Seidler Equity | We depose their investment committees on cost-cutting decisions (Arsenal Angle #11). |
Most firms stop at the local LLC. We go upstream. We know that while the local park may have a $1 million policy, the corporate umbrella and excess layers often reach $25 million to $100 million. Through-Line #13: Every insurance layer exists and we will find it.
Texas Law and Your Rights in the City of Hideaway
Texas law is nuanced, but it is not the barrier the park wants you to believe it is.
Parental Indemnity and Minors (Munoz v. II Jaz):
In Texas, a parent cannot sign away a minor child’s right to sue for personal injuries. Even if you signed the iPad at the kiosk, your child’s personal cause of action survives under Munoz. The park’s legal team knows this, but they count on you not knowing it.
The Waiver Defeat Edge:
Our firm includes associate attorney Lupe Peña, who used to sit on the other side of the table—defending insurance companies and parks. He knows exactly which waiver clauses Texas courts void. We attack on the “Fair Notice” doctrine (Dresser Industries): if the waiver wasn’t conspicuous or didn’t explicitly name “negligence,” it may be unenforceable against even an adult.
Gross Negligence Carve-Out (Moriel):
Texas law (CPRC § 41.001) protects victims from gross negligence regardless of a waiver. If the park knew of a torn mat and didn’t close the court—like in the Cosmic Jump case—the waiver is worthless.
Bilingual Waiver Attacks (Delfingen):
Many City of Hideaway families speak Spanish as their primary language. If the park presented you with an English-only kiosk waiver under time pressure without explaining it, the Delfingen doctrine allows us to challenge the very formation of that contract.

The 48-Hour Evidence Preservation Protocol
The clock is not your friend. While the Texas statute of limitations usually gives you two years (tolled until age 18 for minors), the EVIDENCE clock is set to 7 to 30 days.
- Surveillance DVRs: Most parks overwrite their footage within a few weeks. If we don’t send a spoliation letter within 24 hours of your call, the best evidence of the monitor being on his phone at the moment of your child’s injury will be erased.
- The Incident Report: Parks often “revise” these reports in the days following a trauma. We demand the original metadata to see what was deleted or sanitized.
- The Waiver Kiosk: Databases purge version history on 72-hour cycles. We must capture the exact version of the screen you saw before it is “updated” by IT to look more conspicuous.
Call 1-888-ATTY-911 now. Our spoliation letter is already drafted and goes out via certified mail same-day.
Pediatric Orthopedics: More Than a Broken Bone
Children’s bones are biomechanically distinct. They are more pliable and contain growth plates (physes) that are weaker than ligaments. A “broken leg” at age 8 is often a Salter-Harris Type II fracture of the distal tibia. This damage might not show a leg-length discrepancy or a crooked bone until age 14.
We don’t settle for the current hospital bill. We build a Pediatric Life-Care Plan. We retain a life-care planner and a forensic economist to calculate the next ten years of orthopedic monitoring, the possible corrective osteotomies, the special education accommodations, and the lost adult earning capacity that results from a traumatic childhood injury.
Frequently Asked Questions for City of Hideaway Parents
Can I sue if I signed the waiver?
Yes. In Texas, a parent cannot waive a minor’s direct claim under Munoz v. II Jaz. Furthermore, no waiver in Texas can release a park from gross negligence. If the park violated ASTM F2970—the industry’s own safety floor—we have a case.
What should I do if my child has dark urine after jumping?
Get to an Emergency Room immediately. This is a primary sign of rhabdomyolysis and acute kidney failure. Do not go to urgent care; they do not have the labs needed. Ask for a creatine kinase (CK) blood test. Then call us. Our actively litigated $10 million UH case gives us the medical architecture to prove how the park caused this condition.
The park’s insurance company offered to pay my medical co-pay. Should I take it?
No. This is the “Med-Pay Trojan Horse.” On the back of that check is often a release of all future claims. By taking $3,000 today, you could be giving away a $2 million claim for future surgeries your child will need at age 16.
How long does the park keep video footage?
Typical retention at major chains like Urban Air or Sky Zone is 30 to 90 days, but some overwrite in as little as 7. If you do not have a lawyer send a preservation demand immediately, that video will be gone.
What if I’m not a U.S. citizen?
Your immigration status does not affect your right to a civil recovery for your child’s injury. At Attorney911, all client communications are privileged and confidential. We are a private firm, and our goal is your child’s recovery fund, not your status.
How much does a trampoline park lawyer cost?
We work entirely on contingency. You pay nothing upfront. We pay for the biomechanical engineers, the orthopedic experts, and the forensic digital examiners. We only get paid a percentage of what we recover for you. If we don’t win, you owe us nothing.
Why Choose Attorney911 for Your City of Hideaway Case?

Ralph Manginello brings 25+ years of trial experience and has recovered multi-million dollar settlements for traumatic brain and spinal cord injuries. Our associate Lupe Peña knows the insurance defense playbook because he used to write the arguments they now use against you. We’ve gone toe-to-toe with Fortune 500 corporations and won.
As client Chad Harris said, “You are NOT just some client… You are FAMILY to them.” We represent the families of City of Hideaway. We represent the parent at the trauma-bay bedside. We represent the child whose future was altered by a park that prioritized margin over safety.
What happened to your child at the City of Hideaway trampoline park wasn’t an accident—it was the predictable output of a system. The AAP has been warning since 1999. ASTM F2970 was written by the industry itself to establish a safety floor. The park operated below that floor to hit a profit target. The waiver was drafted by corporate counsel who knew it wouldn’t hold in most Texas contexts. The surveillance is engineered to overwrite before most families have a lawyer. We were built for exactly this fight.
